Description: |
| The fixed and movable jaws resemble a "Stillson" pipe wrench. The adjusting nut for the movable hook jaw sets in a circular opening, and has a spherical exterior. The passage for the shaft of the hook jaw is elongated in the "vertical" plane. This allows the movable hook jaw to position in a range of angles relative to the fixed jaw face.
The shank of the wrench is threaded, and the handle can screw in or out to alter the effective working length of the handle. |
